This is a rare display piece, are you familiar with this website: http://www.theoldrobots.com/Tobor_1.html
What is the asking price and are you considering buying to re-sell or as a collector?
There are no actual past auction records in any of the paid databases I use.
I will opt-out and your question will open again to all the experts. If someone knows the answer they will post a response to you here. You do not need to re-list your question and this does not cost you extra. There is not a guarantee that you will receive a response.
I will not be able to respond back after opting-out
I do hope you find the information that you seek.
